Answer: 180
Step-by-step explanation:
Remember, the exact value cannot involve any rounding or estimates. Now, let's solve this problem. First, we have to translate it into an expression:
√72 - √8 + √128 separate the terms into square roots
√36·2 - √4·2 + √64·2 square root the terms that you can
6√2 - 2√2 + 8√2 they have like radical terms, so combine the terms
6 - 2 + 8 = 12 the coefficients are 12 when combined
12√2 this is the EXACT VALUE of the expression
Hope this helps!
You basically just find the area of all the faces and area you can touch ;)
Answer:
Domain: 0 ≤ x ≤ 4
Range: 0 ≤ y ≤ 64
Step-by-step explanation:
<u>Information</u>
Domain: set of all possible input values (x-values)
Range: set of all possible output values (y-values)
From inspection of the diagram, the minimum value of x is 0 and the maximum value of x is 4.
Therefore, the domain is: 0 ≤ x ≤ 4
From inspection of the diagram, the minimum value of y is 0 and the maximum value of y is 64.
Therefore, the range is: 0 ≤ y ≤ 64
